The test device includes a mobile car 110 and a test channel 120. The test channel 120 contains a four legged structure 127, a top bracket 125, two side brackets 126 and a magnetic labeling 128. The four legged structure 127 is fixed on the ground and includes four vertical brackets placed vertically on the ground and the horizontal bracket that connects the top of the vertical brackets. The top bracket 125 consists of four adjustable axles and two boards that are placed vertically. The two boards are installed on the upper side of the left and right side of the four legged structure 127, while the top of the boards and the four apexes of the four legged structure 127 are in the same plane. The upper side of the two boards has a pair of chutes 121 for inserting the top mental plate 123 from the top. The four adjustable axles are fixed between the two boards and the reader/writer antenna 132 is installed on the axles of the top bracket 125. The side brackets 126 consist of four adjustable axles and two boards that are placed horizontally in the left and right side respectively. The two boards are installed in the middle of the left and right side of the four legged structure 127 and the top of the boards touches the bottom of the boards in the top bracket 125. The four adjustable axles are fixed between the two boards and the reader/writer antenna 133 is installed on the axles. The vertical brackets of the four legged structure 127 have a pair of chutes 122 respectively for inserting two side mental plates 124 from the left and right sides of the four legged structure 127. The top mental plate 123 is inserted along with the chutes 121 from anterior to posterior, while side mental plates 124 are inserted along with the chutes 122 from the top down. The magnetic label 128 is located on the ground, in the right middle of the four legged structure 127, indicating the test driving route from anterior to posterior for the mobile car 110.
The RFID tags 101 are fixed on under-test goods which are loaded and carried by the mobile car 110.
The testing equipment includes a computer 130, a reader/writer 131, a reader/writer antenna on a top 132 and reader/writer antennas on a side 133. The reader/writer antenna 132 is installed on the top bracket 125 and reader/writer antennas 133 are set on the side brackets 126. The computer 130 connects with the reader/writer 131 with RS232 serial port or wireless. The reader/ writer antennas 132 and 133 are connected to the reader/writer 131 with serial port, while to the RFID tags with the RF connection through an air base. The computer 130 controls the reader/writer 131 to send the query command, and then the reader/writer antennas emit electromagnetic waves to request the EPC code of the RFID tags 101. The reader/writer 131 then makes an analysis of the response of the RFID tags 101.
The mobile car 110 is used to carry the under-test goods and the magnetic identification device is installed on the bottom of the mobile car to identify the magnetic label 128 on the ground. With the magnetic identification device, it moves in the test channel 120 based on the test driving route marked by the magnetic label 128. When the mobile car 110 moves to a deviated test driving route, it will adjust to the correct route on the basis of the magnetic label 128. Meanwhile, the mobile car 110 can go forward, move backward, rotate in-situ and regulate the motor speed. The mobile car 110 further contains an ARM development board and connects with a computer 130 with an RS232 serial port and wireless. A program may be downloaded to the ARM development board through the serial port from the computer 130, which realizes the initial control of the mobile car 110. In the test process, the computer 130 sends a control command to control the mobile car 110 in a wireless way.
The top bracket 125, the side brackets 126 and four legged structure 127 are made of the materials that are not sensitive to the UHF radio frequency signals. The reader/writer antenna 132 is located in the middle of the top bracket 125 and adjusts the angle of the ground by means of the adjustable axle in the top bracket 125. The reader/writer antennas 133 are placed in the side brackets 126 and adjust the distance from the ground for electromagnetic wave signals by moving up and down the adjustable axles in the side brackets 126. The reader/ writer antennas 132 and 133 can be adjusted either manually or automatically by the computer 130. For example, the computer 130 uses an angle controller and distance sensors to adjust the reader/writer antennas.
The mental plates 123 and 124 are used to change the test environment and an inner surface of the mental plates 123 and 124 are covered with absorbing materials to reduce the influence on the test results for UHF radio frequency signals.
The magnetic labeling 128 is used to mark the test driving route for the mobile car 110. The mobile car 110 moves in the test channel 120 according to the test driving route marked by the magnetic label 128.
The operating frequency of the RFID tags 101 is between 860 MHz and 960 MHz. An air interface protocol between the reader 131 and the RFID tags 101 accords with the 18000-6 ISO/IEC standard. The reader 131 is a UHF reader. The response of the RFID tags 101 contains the EPC code that can be analyzed by the reader 131.
The computer 130 is a personal computer that contains a mobile car control software and a reader control and analysis software to control the mobile car 110 and the reader/writer 131. The reader control and analysis software is used to analyze the response from the under-test RFID tags 101.
Step 201: Device initialization. A computer 130 is connected with a reader 131 and a mobile car 110. Also the mobile car 110 loads the under-test goods with the RFID tags 101. All devices are ready for work. The mental plates 123 and 124 are not inserted.
Step 202: Adjusting the status of the reader/writer 131 and the reader/writer antennas. First, the connection between the reader and the reader antennas is determined. It can be considered as the case of one reader connected to one reader antenna or one reader connected to multiple reader antennas. And then, the placement of the reader/writer antennas is determined, such as the position, the angle and the number of the reader antennas. The reader/writer antenna 132 is placed in the middle of the top bracket 125 and is adjusted by the placed angle. That is to say, the reader antenna 132 is deflected upward or downward using the horizontal plane as a benchmark. For example, from the horizontal plane, the angle of the upward deflection is increased by 5 degrees to 75 degrees every time, and then the angle of the downward deflection is increased by 5 degrees to 75 degrees. The reader/writer antenna 133 is placed in the side brackets 126 with 0 degree for the vertical axis and is adjusted by the placed height. The height of the reader/writer antenna 133 is determined by the size of the under-test goods with the RFID tags. The angle of the reader/writer antenna can be adjusted manually, or it can be adjusted automatically by the computer with an angle controller. The number of reader/writer antennas in the top and the side of the brackets is gradually increased from 1 to 4 at most.
Step 203: Initializing the speed of the mobile car 110. The computer 130 may set the initial speed of the mobile car as 1 m/s.
Step 204: Controlling the mobile car 110 to pass through the test channel. The mobile car can move to the middle of the test channel 120 in uniform motion, rotate 360 degrees in-situ and then continue to pass the test channel in uniform motion. In this way, the RFID tags 101 in the side of the under-test goods can be identified from multiple angles in a full range so as to improve an identifying rate of the RFID tags.
Step 205: The reader sends a query command to the under-test RFID tags 101. The reader requests to obtain the EPC code of the RFID tags.
Step 206: Determining whether the reader/writer has got the correct EPC code. The reader/writer 131 receives the response of the RFID tags and then sends it to the computer 130. The reader/writer control and analysis software in the computer 130 may determine whether the RFID tags have been identified or not. If a correct EPC code is obtained, go to Step 207; otherwise go to Step 208.
Step 207: Recording the current test conditions, including a speed of the mobile car 110, a connection status of the reader/writer 131 and the reader/writer antennas, the angle of the reader antenna 132, the position of the reader antenna 133 and the insertion status of the metal plate. And then the speed of the car 110 is increased by 0.1 m/s. That is to say, a step of iterative increase in the speed of the mobile car 110 is controlled to be 0.1 m/s, and the new speed of the mobile car 110 equals the sum of the current speed and 0.1 m/s and then, repeating the steps from Step 204 to Step 206.
Step 208: Determining whether the mobile car need to go into the next test cycle or not. One test cycle includes adjusting the status of the reader/writer and the reader/writer antennas and the speed of the mobile car in an invariant external test environment. Specifically, in one embodiment of the present invention, the invariant external test environment means an insertion status of the metal plate is unchanged.
The condition of entering the next test cycle is that the status of the reader and reader antennas is unable to continue to change. If the mobile car 110 enters the next test cycle, go to Step 209; otherwise, back to Step 202.
Step 209: Determining the insertion state of the metal plate. If the mental plates 123 and 124 have been inserted into the four legged structure 127 completely, go to Step 211, otherwise, go to Step 210.
Step 210: Changing the insertion status of the metal plate. The metal plates 123 and 124 are inserted into the four legged structure 127 according to the direction shown in FIG. 1 , and increase the insertion depth by ⅓. Specifically, the mental plate 123 is inserted along with the chutes 121 from anterior to posterior, while the mental plates 124 are inserted along with the chutes 122 from the top to down. And then back to Step 202.
Step 211: Finishing the test and close the test system.
According to the present disclosure, a variety of different test conditions for the correct identifying of the EPC code of the RFID tags can be obtained. In practical applications, the performance test may be individual customized for the RFID tags in different goods. That is to say, an optimized test condition can be selected from the test environment for different goods, so that the RFID tags attached on the different goods will be identified effectively.
